Hi @Nixon Sylvester
Generally this means that the website may not been written well enough to recognise the webOS browser identification string and/or the version of WebKit and other technologies used is not supported by the site. This really does not mean that the site would not work at all, rather that the site provider does not want to spend the time, effort and money to provide the compatibility. To date I have not test my 2022 TV to see what the HMTL5 comparability scores are. I will report back when I have had a chance to do so. It may have been better for LG to have recompiled an existing browser to run on webOS, as building a web browser from scratch is a complicated thing.
